☄️ Eratosthenes (crater)

Eratosthenes crater is a relatively deep lunar impact crater that lies on the boundary between the Mare Imbrium and Sinus Aestuum mare regions. T. W. Webb describes it as having "a widely-terraced wall of very irregular height; the surrounding ground is also very uneven". Patrick Moore calls it "one of the most perfect craters on the Moon." It forms the western terminus of the Montes Apenninus mountain range.
